How Deep Will The Minelab Sovereign Go?
Author: Internet Tip
Although I know the Sov will do 10" on a dime and I have no doubt that you are telling it exactly the way you see it, two things about your story make me a little dubious.
1.If it's certain that the ground had never been disturbed, then it's highly unlikely that a '67 could have been that deep, especially when it's nearby companions were at 3-4".
2.You say it sounded the same as the others before you dug. It shouldn't have. The pitch should have been the same, but the strength of the signal should have been much lower. There are several phenomena you have to be careful of when extracting a coin from a hole to determine it's exact depth. I've had many a coin's dissapear after breaking the ground. There are two major reasons thishappens. The coin, of course, doesn't really disappear. What happens is, it either sticks to the side of the hole on edge, drastically reducing or eliminating the signal, or it drops deep enough into the hole to be out of range. When it disappears, remove ALL loose dirt from the hole plus just a tad more at the bottom (if the hole isn't deep enough for this problem, then it's stuck in the side). If that doesn't get it, scrape the sides of the hole all the way around a couple of times to get it off the side.
On fainter, repeatable good signals, I generally dig very carefully to keep either of these things from happening. I like to know how deep my machine is going for good coins. My depth test for the Sov was on an island park where the soil was always saturated near the shore. This kept the topsoil-like pudding at times, allowing coins to sink faster than normal. I got pulltabs there at 6 and 7 inches. When I finally found the very faint repeatable signal I was looking for, I carefully dug to expose the coin. I wanted to see its imprint in the undisturbed soil underneath it when I removed it (I've seen this lots of times, but usually in the plug or the edge of the hole). When I got to the '37 Merc, I was up to my elbow in the hole. I didn't have a ruler, but it measures 14-15" from my elbow to the second joint of my fingers. That's where the dime was. At the very least, IKNOW it was over 12". Remember, there was also very good soil moisture on this dig. That's important for good depth, too. For signals that still read good after digging 12 inches and not finding it, WIDEN THE HOLE. There are several phenomena that can cause you to be off center enough to miss the target.

I'll never forget the first time I swung a metal
detector and it BEEPED!
I dug up my treasure and I held that shiny circle of metal in my hand--a
quarter!! Wow! A whole twenty-five cents! Since then I have treasured
hunted all over the world. This site has info on kellyco metal detectors and hopefully
anything else you need to know about metal detecting, treasure hunting,
and finding gold!
Good luck!
